It's the world's first bionic eye recipient who in return will offer new insight to scientist.
Australian scientists successfully transplanted the world's first bionic eye prototype into a woman.
Doctors say, patient, Dianne Ashworth has hereditary vision loss.
They say the robotic eye was surgically attached to Ashworth's retina.
The tiny device contains 24 electrodes that send electrical impulses to stimulate her eye's nerve cells.
The researchers switched on the device in their laboratory, after Ashworth had recovered from the surgery.
Her robotic eye only works when it is connected inside the lab.
It will be used to investigate how images are created by the brain and eyes.
Ashworth's vision loss was caused by degenerative retinitis pigmentosa.
